In order to make a fluffernutter, one must first have Fluff. Should one happen to not be in a region where supermarkets carry this delicacy (Fluff is predominantly found in the East Coast of the United States, although the stuff likely be had in the Midwest, amongst other places) it is possible to melt marshmallows and corn syrup and a pinch of gelatin together in a pan on a stove in order to mimic Fluff (but that's a lot of work, you might as well order it off of Amazon.com or someplace). Any sort of easily slice-able bready substance may be used—even cake. While peanut butter is traditional, cashew butter works, as does the less pliable almond butter. Nutella will add an entirely new dimension to the classic fluffernutter.
